First step toward making ccheck.sh useful on hosts other than the commit server.
Added logic to mirror p4d logic of applying 'any' as a global default that can be overridden by a value specific to the current ServerID.
This won't be noted in the release notes; we'll wait until full support for operation on servers other than the commit is complete, including documentation. (Adding full support will require changes to the format of the configurables.cfg file, which is a bigger change).
